Hey guys, looking for info on a PS5 Slim (CFI-2115, EDM-052 board, ADP-400JR PSU).

PS4 games run for hours with zero issues. PS5 games crash after 45–70 mins on cold boot, or within 3–5 mins on a warm restart. Symptom: black screen $\to$ white LED on + fan spinning for 5–10s $\to$ shuts down completely. 1st power button press gives 1 beep, 2nd press boots with 3 beeps.

Confirmed measurements:

• 12V rail under load stays rock solid at 12.06–12.08V right until crash.
• Resistances: VDD_GFX 2.0Ω, VDD_SOC 4.1Ω, GDDR6 1.35V 21.5Ω, MISC 9.6Ω.
• Syscon UART telemetry: TSoCTSoC​ is 51–77 °C at crash time (TENVTENV​ 27–35 °C).
• Syscon errors: always starts with B0088108 (Sonics Bus Error), then exactly 3–4 seconds later 808B0000 / 808B00FF (SSD Watchdog Timeout) and 80830019.

Anyone seen this specific sequence on EDM-040 / EDM-052?
